The invention consists of a window with one or more panels 10 which can rotate about a longitudinal central shaft 11 and are capable of fitting, via their free sides provided with seals, in the edge of another, adjacent panel 10 or of the fixed frame. In accordance with the invention, said panels 10, in the closure position, project from one of the front or rear faces of each one of the beams 13 of the fixed frame and on said faces there are profiles 14 for leaktight closure associated with means for their displacement sliding over those faces, from a first position in which they are separate from the flanks 10a of the panels 10, to a second position, in which they fit against said panels 10, blocking them, with seals in the corresponding zones between profile 14 and panel 10. <IMAGE>
